At 15 units per epoch, sustaining 206 aliases for 12 epochs destroys a large amount of value with no path back to the attacker. Each active identity pays a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. The fee repeats 30 times over. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":3,"sig":"2Zzeni7wSvBcEgjhdJcsrWmgvmQsjHyo3RorQCWQ9xQNHGydr76YUoaTtzTR93GVTzHL9jGtjhPitzPeYd6BbDN3"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:57.494Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
